Interface 89C52 with 7135

i am interested in doing with 89C52. And now I trying to use AT89C52 and ICL 7135. And I use nterrupt 0 to get BCD data from ICL7135. I send you my program here and expect to get your advice soon.

I have made a circuit for you to study, also some idea about the code. you need to have Adobe Acrobat Reader

You can find it here Microcontroller you can now try to write the code and draw the circuit you need.

This circuit is an interface between 89C52 of Atmel with 7135 of Intersil. With This circuit you can read analog data of both polarities you can change the range scale with extra circuits, you can store data on a EEPROM or send them to PC thru RS232 or Comm port.
